COMPOSITION COMPRISING SPECIFIC HYPERBRANCHED COPOLYMERS AND 1,3-PROPANDIOL AND/OR N-HYDROXYOCTANAMIDE
The present invention relates to a composition comprising a specific hyperbranched copolymer (HBC) of the monomers dodecenyl succinic acid anhydride, diisopropanol amine and bis-dimethylaminopropyl amine and the compound 1,3-propandiol and/or N-hydroxyoctanamide. It has been found that said hyperbranched copolymer synergistically enhances the antimicrobial action of a 1,3-propanediol and/or N-hydroxy-octanamide.

IODO-FUNCTIONALIZED POLYMERS AS MASS SPECTROMETRY CALIBRANTS WITH A MASS-DEFECT OFFSET
The present invention discloses novel calibrants containing between 1 and 5 iodine atoms and methods of making them using linear polymers, hyperbranched polymers, and biological polymers (including but not limited to proteins and peptides.) Methods of using the calibrants are also disclosed, such as mass spectrometry. The novel calibrants disclosed herein have a more cost- and time-efficient synthesis than other calibrants.
DENDRIMER-BIOADHESIVE POLYMER HYDROGEL NANOGLUE AND USE THEREOF
A nanoglue is formed with one or more bioadhesive polymers, one or more dendrimers, and optionally one or more therapeutic, prophylactic, or diagnostic agents. The bioadhesive polymers and dendrimers are modified with functional groups to permit crosslinking upon one or more stimuli, e.g., ultraviolet irradiation, and form hydrogel in situ at tissue sites. In the repair of corneal wounds, the nanoglue leads to improved rate of healing with less scarring and less inflammation, compared to non-treated cornea or ones treated with sutures. Therapeutic agents can be covalently conjugated to the precursor components and be delivered to specific eye compartments, providing a more efficacious treatment formulation of ocular disorders than delivering drugs in their free forms. Methods of making and using the hydrogel and hydrogel precursor compositions are also provided.

CURABLE DENTAL TWO-PACK COMPOSITION
The present invention is related to a curable dental two-pack composition comprising: (a) a first paste comprising (a-1) one or more crosslinker having at least four primary amino groups; and (b) a second paste comprising (b-1) one or more compounds polymerizable with a crosslinker of the first paste in a step-growth polymerization reaction; wherein (b-1) the compound polymerizable with the crosslinker compounds is a compound of the following formula (II):
##STR00001## wherein A is a hydrocarbon group which may contain one or more hetero atoms selected from oxygen and sulfur atoms: R.sup.1 is as defined in claim 1; R.sup.4, R.sup.5, R.sup.6 and R.sup.7 are independent from each other and represent a hydrogen atom or a methyl group and the Y, which are independent from each other represent a single bond, an oxygen atom, a sulfur atom, an ester bond or a urethane bond.
